I am looking for software to backup Outlook POP accounts and was testing Mail Archiver X (Maverick and Outlook and MAX are all the latest versions).

Running MAX crashes Outlook somewhere in the middle of the run.  I have been in contact with the developer and she said that Outlook is corrupted.  I rebuild the identity and immediately ran MAX and it crashed again.  My question is can Outlook still have corruptions after a rebuild?  And how to fix?  Thanks.
